Workshop Heating and Cooling

My shop:

  • 20’6” x 20’6” with a 10’ ceiling.
  • All perimeter walls, except 12’ of one wall attached to my house, are not insulated.
  • Garage door is a regular 2 car garage door that I added insulation to. Two kits needed for my door.
  • Garage door has wide weatherstripping attached to the outside.
  • Ceiling above is not insulated.

My local climate:

  • I live in central Mississippi which is known to have a high annual precipitation level.
  • Mississippi also has a high average temperature.

Previous heating:

  • Two 1500w electric radiant heaters. They couldn’t keep up with the space.
  • Two electric radiant heaters + a small propane Mr. Heater one plaque 4,000-9,000-BTU Indoor-Safe Portable Radiant Heater. This worked but didn’t burn as efficient as I had hoped and produced an odor that we could smell inside the house.

Previous cooling:

  • Box fan. Even a steady breeze is still miserable in the high heat and humidity of the Southeast climate.

Current setup:

  • QuietSide brand mini split AC & heat pump unit. Model number QS18-VJ220.
  • 18,000 BTU cooling and 19,800 BTU heating.
  • Comfortably cools to low 70’s in the summer time and drastically reduces the humidity in the shop.
  • Comfortably heats the shop in the winter time. Although, the lowest setting is 61 degrees which is a little warm for working in the winter time. I’d prefer to work in a long sleeved shirt or light jacket in the winter and remove the long sleeves in the event that I get hot.
  • The outside unit is a lot quieter than the unit for my house.
